WASHINGTON — President Barack Obama will travel to Denmark to support Chicago's bid for the 2016 Summer Olympics, projecting the highest-ever White House profile in lobbying for the international event.

Valerie Jarrett, a senior adviser to the president, told The Associated Press Monday morning that Obama will leave Thursday and join his wife, Michelle, in Copenhagen, where they'll make the pitch to the International Olympic Committee. Obama would be the first U.S. president to actually appeal in person to the International Olympic Committee for an Olympics event.

The International Olympic Committee is meeting in Copenhagen to select a host city for the 2016 Summer Games. Chicago faces tough competition from Rio de Janeiro, Madrid and Tokyo.

The White House later formally announced the trip, saying that Obama and his wife "will both make presentations to the IOC during Friday's session. They will discuss why Chicago is best to host the 2016 Summer Games, and how the United States is eager to bring the world together to celebrate the ideals of the Olympic movement." The IOC is scheduled to decide the site on Friday.

While in Denmark, the statement said, Obama and his wife also will meet with Queen Margrethe and the president will meet with Prime Minister Lars Loekke Rasmussen of Denmark.

Obama, who represented Illinois in the U.S. Senate after serving in the Illinois Legislature, is a longtime supporter of Chicago's bid. Michelle Obama is a native of the city and he considers it his adopted home town. Obama recently sent letters to selected IOC members promising a "spectacular Olympic experience for one and all."

"President Obama and First Lady Michelle Obama symbolize the hope, opportunity and inspiration that makes Chicago great, and we are honored to have two of our city's most accomplished residents leading our delegation in Copenhagen," Mayor Richard M. Daley said in a statement. "Who better to share with members of the International Olympic Committee the commitment and enthusiasm Chicago has for the Olympic and Paralympic Movement than the President and First Lady."

The president had held off on announcing a trip to Copenhagen, saying his first priority was the ongoing debate in Washington over health care reform. But aides said the president determined that his trip wouldn't take away from that process. The legislation is a signature piece of his domestic policy agenda and negotiations on Capitol Hill have been contentious.

But with heads of state representing Rio and Madrid already scheduled to attend the IOC meeting Friday, Chicago's bid organizers had hoped Obama would make an in-person appeal.

"I don't think there's an IOC member on the planet that wouldn't love to meet your president. He's a transformational figure in the world today," longtime IOC member Dick Pound said recently.

Obama is also mobilizing his administration on behalf of Chicago's bid. Senior adviser Jarrett, Education Secretary Arne Duncan and Transportation Secretary Ray LaHood, will also be joining the president and first lady in Copenhagen. All are from Illinois.

They join a Chicago contingent already packed with more star power than a Hollywood red carpet. The first lady is one of the few people who rivals her husband in visibility, and she'll be joined by talk show host Oprah Winfrey, who trails only Angelina Jolie on Forbes' annual Celebrity 100 list, a ranking of the rich and famous' most powerful.

Chicago is also bringing 14 Olympic and two Paralympic gold medalists, including Michael Johnson, Jackie Joyner-Kersee, Nadia Comaneci and Nastia Liukin.
